Part Descriptions

LP157588-7 Leukocytes
Leukocytes or white blood cells (WBCs) are immune cells that fight infection, neoplasms and other inflammatory conditions, and mediate allergic responses. There are five types of WBCs normally present in the circulation that are all derived from a similar stem cell in the bone marrow. The five type of WBCs are divided into two groups based on the presence or absence of granules in the cytoplasm. The granulocytes include the neutrophils, basophils and eosinophils. The non-granulocytes include the lymphocytes and the monocytes. The neutrophils fight infection by ingesting and digesting bacteria. Eosinophils and basophils respond to allergic reactions and are capable of ingesting antigen-antibody complexes. Monocytes phagocytose bacteria and release interferon to stimulate the immune system. Lymphocytes are divided into T-cells and B-cells. T-cell immunity is cellular and involves the activation of phagocytes and B-cell immunity uses antibodies to fight infection. Both elevated and low leukocyte counts can be markers of infection and malignancy, and low leukocyte counts are associated with a variety of primary and secondary immunodeficiencies, depending on the WBC type(s) that are out of range.

LP18691-3 Lymphocytes.clefted
Clefted (fissured) lymphs are usually associated with CLL. This white blood cell is found in the bloodstream of a patient with malignant lymphoma. The nucleus is a bit large for a normal lymphocyte, without a corresponding increase in cytoplasmic size as you'd expect in a reactive lymphocyte. The groove in the nucleus corresponds to a stage in lymphocyte development in germinal centers. One should not see these cells in the circulation. This is cancer. Source: Regenstrief LOINC

Basic Attributes

Class: HEM/BC
Type: Laboratory
First Released: Version 1.0k
Last Updated: Version 2.79 (NAM)
Change Reason: Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component; Previous Releases: Changed Component name 'Lymphocytes.fissured' to the more common name.
Order vs. Observation: Observation
